What this book covers

Chapter 1, Getting Started with openFrameworks, introduces openFrameworks by explaining its installation and running one of its examples. Additionally, it discusses the structure of the video synthesizer project, which will be developed in the course of the book.

Chapter 2, Creating Your First openFrameworks Project, guides you to create a new openFrameworks project and implement 2D graphics.

Chapter 3, Adding a GUI and Handling Keyboard Events, explains creating a graphical user interface consisting of controls such as sliders and checkboxes. Also, it covers implementing keyboard events, using system dialogs, and saving screenshots.

Chapter 4, Working with Raster Graphics – Images, Videos, and Shaders, explains drawing images and videos, capturing video from a camera, mixing videos using additive blending, and creating the kaleidoscope video effect using a fragment shader.

Chapter 5, Creating 3D Graphics, introduces the basics of 3D graphics with openFrameworks by drawing a sphere in 3D and then texturing and deforming it.

Chapter 6, Animating Parameters, discusses using various data sources, such as Perlin noise, sounds, and text files, to automatically control the parameters of the project.

Chapter 7, Distributed and Physical Computing with Networking and Arduino, explains how to control your project from other programs using the OSC networking protocol. It describes building such controlling programs using openFrameworks by itself as well as the Python and Max/MSP programming languages. Also, it covers receiving data from an Arduino device.

Chapter 8, Deploying the Project on iOS, Android, and Raspberry Pi, guides you to run the light version of the developed video synthesizer on mobile and Raspberry Pi devices.

Chapter 9, Further Resources, suggests the direction to further enhance the video synthesizer project, provides sources of additional information on openFrameworks, and discusses debugging and speeding up openFrameworks projects.

Appendix A, Video Synthesizer Reference, is a comprehensive documentation of the developed video synthesizer project. It contains a description of all GUI controls, control keys, and media files used by the project.

Appendix B, openFrameworks Quick Reference, is a useful reminder of the basic openFrameworks functions and classes used in the book.
